Dear ALL,
IHAC who would like to use Sun Fire X4500 to be the NFS server for the
backend services, and would like to see the potential performance gain
comparing to their existing systems. However the outputs of the I/O
stress test with iozone show the mixed results as follows:
* The read performance sharply degrades (almost down to 1/20, i.e
from 2,000,000 down to 100,000) when the file sizes are larger
than 256KBytes.
* The write performance remains good (roughly 1,000,000) even with
the file sizes larger than 100MBytes.
The NFS/ZFS server configuraion and the test environment is briefed as
* The ZFS pool for NFS is composed of the 6 disks in stripping with
one on each SATA controller.
* Solaris 10 Update 5 (Solaris Factory Installation)
* The on-board GigE ports are trunked for better I/O and network
throughput.
* Single NFS client on which the I/O stress tool iozone is deployed
and run.
Attached the iozone output, and some outputs extracted from the attached
file are presetned later in this email. Any inputs, like NFS/ZFS tuning,
troubleshooting, etc., are very welcome. Many thanks for your time and
support.
Regards,
Matthew
